*
* smpte can accept I420 video streams with the same width, height and
* framerate. The two incomming buffers are blended together using an effect
* specific alpha mask.
*
* The #GstSmpte:depth property defines the presision in bits of the mask. A
* higher presision will create a mask with smoother gradients in order to avoid
* banding.
